H S determination in solid and pasty samples2

Product description

H S Headspace Module for coupling to Sulfimax GX 2

analysis systems of ECH

Sulfimax GX Go with connected Headspace Module

Applications

The sample is filled into a glass vial and heated in the headspace

module. Depending on the sample type, the heating temperature

can be varied from 30 to 180 °C. The volatile H S is transported 2

through the gas circulation to the sensor in the Sulfimax GX

and measured there. Very low H S concentrations are detectable. 2

Sample preparation is not necessary.

The determination of volatile hydrogen sulphide (H S) in solid 2

and pasty samples is now very easy. The selective H S analysis 2

system Sulfimax GX of the ECH is extended with a manual

headspace module.

Due to the short determination times, high sample throughputs

are possible. The compact and robust device can be easily

operated by anyone.

H S Headspace Module2

sulfimax GX

· solid samples, e. g. elementary sulphur, sludge, bitumen,

· pasty samples,

· liquid samples such as wastewater with sludge particles,

H S analysis systems from ECH, coupled with the Headspace 2

Module allow the measurement of:

· soil samples and waste

Advantages

· Very low H S concentrations detectable2

· No sample preparation necessary for solid samples

· Manually operated and robust measuring system

· Easy handling for everyone

· Easy connection to the Sulfimax GX Lab and Go
